SAME WITH ME PLEASE HELP!!!

Did you get some solution of problem then please reply. I am in same problem.

Your query is a bit complex. I have a few questions to ask you too so that I can help you with your query.

First of all when you filled the form didn't you get any message or notification from NTA saying that you are already registered? Did you change some sort of details in your form different from the previous time you filled it? If your application form is not showing any option for cancellation then I would suggest you, visit the NTA website of Jee mains and try to contact them.

There are few telephones no(s) given their: 7042399521, 7042399525, 7042399526

Also, you can even email them your query on jeemain-nta@nic.in.

Hope they can help you if that doesn't work then feel free to ask for further help.

Goodluck
